Longhorned Borer Beetle

Dear John, This is a Longhorned Borer Beetle in the family Cerambycidae and though they have strong mandibles, they are not prone to biting unless they are carelessly handled. This is not the creature that is biting you at night and which caused you to spray insecticide, but it is collateral damage as insecticide is rarely selective.
